Non esterified fatty acid levels in Indian cross bred jersey cows under small holder farming systems

Abstract

Data on Production diseases assessment in Indian dairy cattle is less. The objective of this study was to assess the Non-esterified fatty acids level in three different small holder farms of Cauvery Delta region of Tamilnadu. Sixty cross bred dairy cattle were selected at different levels of lactation in the three farms. Serum samples were analyzed for non esterified fatty acids (NEFA). Mean ± standard deviations of the values were arrived and the data were statistically analyzed. NEFA values of early, mid, late lactation, Far off dry and close up dry cows were 0.39±0.09, 0.24±0.03, 0.19±0.03, 0.18±0.03 and 0.23±0.03mmol/L, respectively. No significant variations were recorded in between the farms. Cows at early lactation had higher NEFA concentrations where as lowest concentrations was observed in Far off Dry cows.
